Multi-Currency Merchant Accounts & International Card Payments: UK Business Guide

Multi-Currency Merchant Accounts & International Card Payments: UK Business Guide

 Taking card payments from customers in different countries is not simply a case of switching on another currency at checkout.

A UK business selling internationally may need to consider where transactions are acquired, which currencies customers can pay in, which currencies the business can settle in, foreign exchange costs, cross-border charges, payment gateway support, local payment methods and how the whole payment flow is structured.

For some businesses, a standard UK merchant account with multi-currency functionality is enough.

For others, particularly businesses with significant international turnover, multiple entities, higher-risk sectors or customers across several regions, the payment setup can become considerably more complex.

Merchant Advice Service helps businesses understand these requirements and identify payment providers whose services may suit their individual payment structure. International payment strategy involves more than simply accepting additional currencies. Explore our Payments Strategy Library for guidance on local acquiring, international expansion, payment performance and provider structure. You can read more about how Merchant Advice Service works.

What Is Multi-Currency Payment Processing?

Multi-currency payment processing allows a business to accept card payments in more than one currency.

For example, a UK ecommerce business might allow customers to pay in:

• GBP

• EUR

• USD

The important point is that accepting a payment in a currency and receiving settlement in that currency are not necessarily the same thing.

A business could allow a customer to pay in euros but still have those funds converted into pounds before settlement.

Alternatively, depending on the provider and banking setup, the business may be able to settle euro transactions into a euro-denominated account.

That distinction can have a significant effect on FX costs and how international revenue is managed.

What Is the Difference Between Presentment Currency and Settlement Currency?

This is one of the most important distinctions for businesses comparing multi-currency payment providers.

Presentment currency

The presentment currency is the currency shown to the customer when they pay.

For example:

Product price: €150

The transaction is presented to the customer in euros.

Settlement currency

The settlement currency is the currency the merchant ultimately receives from its payment provider.

The €150 transaction could therefore:

1. Be processed in EUR and settled to the merchant in EUR, or

2. Be processed in EUR and converted before being settled to the merchant in GBP.

The second route introduces a currency conversion.

Businesses processing substantial international volume should therefore look beyond the number of currencies a provider says it "supports".

Ask:

• Which currencies can customers pay in?

• Which currencies can I settle in?

• Can I settle each currency without conversion?

• Which bank accounts can settlements be paid into?

• Who performs the FX conversion?

• What exchange rate is used?

• What markup or conversion fee applies?

These questions often provide a much clearer picture of the real cost of multi-currency processing.

Do I Need a Multi-Currency Merchant Account or a Multi-Currency Payment Gateway?

Potentially both.

The merchant account and payment gateway perform different roles.

A payment gateway handles the technical transmission of online payment information.

The acquiring or merchant-account arrangement determines whether the transactions can actually be accepted and where funds are ultimately settled.

A gateway may technically support dozens of currencies while the acquiring arrangement behind it supports fewer settlement currencies or countries.

Likewise, an acquirer may support international processing but require a compatible gateway to deliver the checkout experience the business needs.

For an international ecommerce business, you should therefore check both:

Gateway requirements

• Supported checkout currencies

• API support

• Ecommerce platform integration

• Tokenisation

• Recurring payments

• Alternative payment methods

• Fraud tools

• 3D Secure

• Reporting

• Multiple merchant accounts or MIDs

• Payment routing

Acquiring requirements

• Merchant location

• Customer locations

• Supported sectors

• Supported currencies

• Settlement currencies

• Acquiring countries

• Processing volumes

• Transaction values

• Chargeback profile

• Risk appetite

A provider should make clear which part of the payment stack it is supplying.

What Is Cross-Border Acquiring?

Cross-border acquiring generally refers to a payment arrangement where the merchant, customer, card or acquiring relationship spans different countries or regions.

For a UK business selling internationally, the important question is not simply:

Can this provider accept an overseas card?

Most international payment strategies need to look more deeply at:

• Where the merchant is incorporated

• Where customers are located

• Where the transaction is acquired

• Where settlement takes place

• Which currency the transaction uses

• Whether currency conversion occurs

• Whether local acquiring is available

• Whether cross-border charges apply

For a small business with occasional international sales, a simple international payment setup may be sufficient.

For a business processing substantial volumes across Europe, North America or other regions, the acquiring structure deserves much closer attention.

Find Your New Processor

What Is Local Acquiring?

Local acquiring means transactions are acquired within, or closer to, the market in which the customer is paying, subject to the provider's structure and availability.

For businesses with significant international volume, this can be worth exploring because payment cost and payment performance are affected by more than the headline merchant service charge.

Our guide on how high-turnover businesses audit payment fees explains why international merchants should review acquiring location, cross-border charges, FX, settlement and payment performance together.

Local acquiring is not automatically the best solution for every business.

The additional complexity of maintaining multiple acquiring relationships, entities, bank accounts or payment providers also needs to be considered.

Multi-Currency Payments vs Dynamic Currency Conversion

Multi-currency processing and Dynamic Currency Conversion, usually called DCC, are not the same thing.

Multi-currency pricing

With multi-currency pricing, the merchant offers goods or services in different currencies.

For example, an ecommerce website might display:

£100 for UK customers

€118 for European customers

$135 for US customers

The merchant determines the currencies it wants to offer as part of its pricing and payment setup.

Dynamic Currency Conversion

DCC occurs when a cardholder is offered the option of paying in their home currency rather than the merchant's local transaction currency.

For example, a US customer visiting a UK business might be given the choice to pay in GBP or have the transaction converted and displayed in USD.

Visa requires customers using DCC to be shown information including the transaction amount in both currencies, the exchange rate and any additional markup or fees. Customers must also be given the choice to accept or decline the conversion.

You can read Visa's explanation of Dynamic Currency Conversion.

Mastercard also publishes merchant rules and guidance covering Dynamic Currency Conversion.

Businesses should therefore avoid treating DCC as simply another name for multi-currency payment processing.

How Much Does Multi-Currency Payment Processing Cost?

There is no standard multi-currency processing rate.

The total cost can include several different elements.

Depending on the provider and payment structure, these may include:

• Merchant service charges

• Gateway fees

• Cross-border charges

• Scheme fees

• Acquirer or PSP markup

• Foreign exchange conversion

• Settlement fees

• International card charges

• Chargeback fees

• Additional merchant-account or MID fees

• Alternative payment method fees

This is why comparing providers using only a single advertised percentage can be misleading.

For businesses processing meaningful international volume, the better question is:

What does it cost from customer payment through to usable settlement in my bank account?

Where Do FX Costs Appear in Card Payment Processing?

FX costs can appear in several places.

For example, imagine a UK business sells a service for €1,000.

If the customer pays €1,000 and the business ultimately receives GBP, somebody has to convert those euros into pounds.

Depending on the payment structure, that conversion could be performed by:

• The payment provider

• The acquirer

• A banking partner

• Another FX provider within the payment flow

The business should understand:

1. At what point conversion occurs

2. Which exchange rate is used

3. Whether a separate FX markup applies

4. Whether settlement in the original currency is available

5. Whether the business could avoid conversion by using an appropriate currency account

For businesses with large international volumes, small differences in FX pricing can become commercially significant.

Should I Settle International Payments in GBP or the Original Currency?

It depends on what the business does with the funds.

A UK business that receives occasional euro transactions but conducts virtually all of its expenditure in GBP may prefer simple GBP settlement.

A business that receives substantial EUR income and also pays suppliers, staff or other costs in euros may have a stronger reason to investigate EUR settlement.

The same principle applies to USD and other currencies.

Before deciding, consider:

• How much volume is processed in each currency?

• Does the business have costs in that currency?

• Will the funds ultimately need converting anyway?

• What does the payment provider charge for conversion?

• What does the banking or FX provider charge?

• Is settlement to a foreign-currency account supported?

• How does finance reconcile transactions across currencies?

There is no universally correct settlement structure.

The right setup depends on the business's wider financial and operational requirements.

What Is a Multi-Currency Merchant Account?

The phrase "multi-currency merchant account" is often used to describe an acquiring arrangement that allows a merchant to process transactions in more than one currency.

However, providers structure these services differently.

A business might have:

• One merchant relationship supporting multiple currencies

• Multiple merchant IDs

• Different merchant accounts for different regions

• Several acquiring relationships

• One gateway connected to multiple acquirers

• A payment orchestration layer managing different providers

The most suitable structure depends heavily on business scale and complexity.

Small businesses usually benefit from simplicity.

Larger international merchants may have stronger reasons to consider a more sophisticated payment architecture.

Do I Need Multiple Merchant IDs for Different Currencies?

Not necessarily.

A Merchant ID, or MID, identifies a merchant within an acquiring relationship.

Some providers can support several currencies through a single broader setup.

Others may use different MIDs according to:

• Currency

• Country

• Website

• Legal entity

• Business model

• Payment channel

• Acquiring route

Businesses should not assume that more MIDs automatically creates a better payment setup.

Each additional merchant account can also create:

• More reconciliation

• More reporting

• Additional contractual relationships

• More settlement accounts

• Additional technical configuration

• More operational oversight

The payment architecture should reflect a genuine commercial or technical requirement.

When Does Payment Orchestration Become Relevant?

For a business processing through one provider in a handful of currencies, payment orchestration may be unnecessary.

It becomes more relevant when payment infrastructure becomes fragmented.

For example, a larger international business might have:

• One acquirer for UK transactions

• Another for European transactions

• Different payment methods by country

• Several currencies

• Multiple gateways or PSPs

• Different routing requirements

• Backup acquiring relationships

A payment orchestration platform can provide a layer between the business and multiple payment services.

Our guide to payment orchestration explains how this model works in more detail.

Orchestration is not automatically necessary simply because a business accepts multiple currencies. It is more relevant where the wider payment architecture justifies the additional infrastructure.

International Payments Are About More Than Currency

One mistake businesses make when expanding internationally is focusing exclusively on currency.

A customer in another market may not simply want to pay in their local currency. They may also expect a different payment method.

Depending on the market, businesses may need to consider:

• Cards

• Digital wallets

• Bank payments

• Local bank transfer methods

• Domestic card schemes

• Alternative payment methods

Our guide to Alternative Payment Method gateways explains how businesses can support different payment methods through international payment infrastructure.

This is particularly important when building a payment strategy for several countries.

The question should therefore be:

How do customers in this market want to pay?

Not simply:

Which currency do they use?

Multi-Currency Payments for Subscription Businesses

Subscription and recurring-payment businesses have additional considerations.

A business may acquire a customer when an exchange rate is at one level and continue charging that customer months or years later.

International subscription businesses therefore need to think about:

• Billing currency

• Settlement currency

• Recurring transaction support

• Stored payment credentials

• Failed-payment recovery

• Card expiry

• Customer communication

• Refunds

• Chargebacks

• FX exposure

Businesses should also establish whether recurring payments are supported across all required countries and currencies.

Read our full guide to subscription payment processing.

Can High-Risk Businesses Accept Multiple Currencies?

Potentially, yes.

However, international processing can add another layer to an already complex merchant-account application.

A provider may want to understand:

• Business sector

• Merchant Category Code

• Countries being targeted

• Customer location

• Transaction currencies

• Settlement currencies

• Expected volumes by country

• Chargeback exposure

• Regulatory requirements

• Delivery times

• Previous processing history

• Where the business is incorporated

• Where management operates

A high-risk business may therefore need a provider that supports both the business model and the international payment requirements.

A provider being willing to accept a particular sector does not automatically mean it can support every country or currency required.

See our guide to payment gateways for high-risk merchants for more information.

What Should an International Business Tell a Payment Provider?

The more complex the payment requirement, the more important it becomes to clearly describe the required setup.

Before approaching providers, prepare a summary containing:

Business structure

• Legal entity

• Country of incorporation

• Trading locations

• Other group entities

Customer geography

• Main customer countries

• Percentage of revenue by region

• Restricted or excluded countries

Currency requirements

• Currencies customers need to pay in

• Expected volume in each currency

• Required settlement currencies

Payment channels

• Ecommerce

• Face to face

• Telephone payments

• Payment links

• Recurring payments

Commercial profile

• Annual or monthly processing volume

• Average transaction value

• Maximum transaction value

• Existing provider

• Processing history

Technical requirements

• Ecommerce platform

• API

• ERP

• CRM

• Subscription platform

• Booking system

• Reporting requirements

This is more useful than simply asking a provider whether it offers "international payments".

How Do I Compare Multi-Currency Payment Providers?

Do not compare them purely on the number of currencies advertised.

Instead, ask each provider the same questions.

Currency

• Which presentment currencies do you support?

• Which currencies can you settle?

• Can I avoid automatic conversion?

Acquiring

• Where will transactions be acquired?

• Is local acquiring available?

• Which countries can you support?

FX

• Who performs currency conversion?

• Which rate is used?

• What markup is applied?

Fees

• Are there cross-border charges?

• Are international cards priced differently?

• Are additional MIDs chargeable?

• Are there settlement fees?

Technical

• Does the gateway support the currencies I need?

• Does my ecommerce platform integrate?

• Are recurring payments supported?

• Can I add local payment methods?

Operational

• Can reporting separate currencies?

• How are refunds handled?

• In which currency are chargebacks recorded?

• How does reconciliation work?

The "best" provider is the one whose commercial, technical and geographic capabilities match the actual requirement.

Multi-Currency Payment Processing Case Study

Merchant Advice Service has previously helped a UK online business that needed to accept both GBP and EUR card payments.

The requirement was not simply to find a payment company.

The business needed a payment route capable of supporting both currencies while working with its online payment requirements.

You can read the Merchant Advice Service multi-currency payment processing case study.

This is a useful example of why the payment requirement should be established before choosing the provider.

How Merchant Advice Service Helps With International Payments

Merchant Advice Service works with businesses that have straightforward and more complex payment requirements, including businesses requiring international acquiring, multiple currencies and overseas coverage.

1. We establish what the business actually needs

We look at customer countries, currencies, processing volume, payment channels, business sector, existing providers and technical requirements.

2. We separate the different requirements

International payments can involve acquiring, gateways, FX, settlement, currencies and payment methods.

Understanding which elements are actually required makes provider comparison easier.

3. We identify potential provider routes

Where possible, we identify providers or specialist brokers whose services appear relevant to the requirements supplied.

4. The provider completes its own assessment

The payment provider determines its own pricing, supported countries, currencies, underwriting, settlement arrangements and final acceptance.

Looking for a Multi-Currency or International Payment Provider?

International payment processing is rarely just a question of finding a provider that accepts euros or dollars.

The right setup depends on where your customers are, which currencies they use, where transactions are acquired, how you want funds settled and how the payment technology integrates with the rest of your business.

Merchant Advice Service can help you understand those requirements and identify payment-provider routes that may be suitable.
